AUTOMATIC GRAIN WEIGHING AN D REGISTERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 350,658, dated October 12,1886.

A pplieaiion file-.l pril 6, 1886. Serial $0,197,952. (No model.)

To all whom it may concern.

Be it known that I, OURris L. Buncnss, of Woodhull, in the county of Henry and State of Illinois, have invented a new and Improved Automatic Grain Veighing and Registering Apparatus, of which the following ,is a full, clear, and exact description.

The object of my invention is to provide a new and improved apparatus for automatically weighing and registering grain.

The invention consists in the construction and combination of parts, as hereinafter described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the ligures.

Figure 1 is a side elevation of my improvement. Fig. 2 is a vertical cross-section of the same on the line :0 w, 1. Fig. 3 is a rear side view of the same. Fig. iis a vertical longitudinal section of the same on the line y y, Fig. 2. Fig. 5 is a sectional view of the chute on the line Fig. l.

The apparatus A is mounted on a suitable frame, B, forming a box or casing, O, on the inner surface of one side of which are pivoted the arms D D, 011 which are mounted the trunnions E and E, attached to the cylinder F, provided in its periphery with the openings F and F placed opposite each other, and

also provided with the partition F, dividing the cylinder F into two compartments, G and H. The outer ends ,of the arms D are connected by means of a cross-bar, D, which is connected by the link I with the weighingbeam J, fulcrumed on a suitable standard at tached to the frame 13, and provided with a weight, K, adjustable on the said weight-beam J by means of the set-screw K. ()ne arm D rests in its uppermost position against a stop, L, attached to the inside of the box 0. The trunnion E extends to the outside of the box 0, and is provided with a sprocket-wheel, M, which is connected by the chain M with the sprocket-wheel N, said wheel N being of half the size of the wheel M, and being mounted on the shaft X, to which is attached by means of a set-screw, N, an arm, N, the lower end of which is held against the arm 0, fulcrumed at O 011 the frame B, and connected by the crank O with the arm I, hung on the trunnion E. The sprocket-wheel M has on its outer face two lugs or pins, Q and Q, which engage alternately with the lever R of a registering mechanism, II, which may be of any suitable construction. The sprocket-wheel M engages with the pawl AI", which prevents the said sprocket-wheel and the cylinder from revolving in the wrong direction. The other trunnion, E, also extends to the outside of the box C, and is provided with a cam, 8, having two teeth, S and S, which alternately support one end of the lever T, fulcrnnied 071 the frame 13, and connected by the link U with the lever V, fulcruined on a bracket attached to the main frame B, and connected by the links V with a slide, V which operates in grooves formed in the sides of the chute \V. The said chute IV is provided with a partition, \V, dividing its lower end into -wo cischargeconr partments, and having the inner sharp edge, \V, for preventing the grain passing down the chute \V from clogging. A hopper, C, is formed near the lower end of the box 0, and is provided with the central outlet, 0

The operation is as follows: The apparatus is to be placed on top of athrashirig-machine, and the grain to be weighed and registered is carried from the grain-discharge spout of the thrashing-machine to the spout V of the apparatus A by an elevator of suitable construction. As the slide V is open,the grain passes into one of the compartments, G or H, of the cylinder F, and as soon as one bushel of grain has run into the said compartment the weight of the cylinder and its contents is sufficient to overcome the weight K on the beam J, and the cylinder F swings downward on its arm D, which causes the slide V to close the chute IV, as the tooth S or S which. supports the lever T, moves downward and permits the lever T to drop. At the same time the arm 1? moves downward with the cylinder F and discngages the fLlIGl'timOCl arm O by means of the link 0, so that the cylinder, on account of theinclined position of the partition F, will turn on the trunnions E and E, in the direction of the arrow a, and discharge the grain through the opening F or F in the periphery of the cylinder F. The cylinder makes a half-revolution, and thereby causes the sprocket-wheel N ive compartment.

to make a full revolution, so that the arm N also rotates once, and is again locked in the position shown in Fig. 3, by the pivoted arm 0, said arm having returned to its former position on the upward movement of the cylinder F,W\11i0h takes place as soon as all the grain is discharged from the respective compartment and before the arm N has made a complete revolution. The upward movement of the cylinder F is caused by the weight K acting on the pivoted arms D, supporting the cylinder F. The chute W is also opened by the upward movement of the cylinder F, which causes one. of the teeth, S or S to lift the lever T, which operates the slide V by means of the link U and lever V, so that the other compartment is filled with grain, and the operation above described is repeated. During each half-revolution of the sprocket wheel M one of the pins, Q or Q, operates on the lever B of the registering apparatus R, and registers one bushel,or the amount contained in the respect The adj ustability f the arm N on the shaft N of the sprocket-wheel N, permits of setting the arm N at any angle in relation to the central partition, F, of the cylinder F, whereby the discharge of the grain from the compartments can be regulated.

Having thusfully described my invention, I claim as new, and desire to secure by Letters Patent p 1. In a weighing and registering apparatus, the combination of a cylinder having two compartments and trunnions, pivoted arms supporting the cylinder, and a weighing -beam connected with the pivoted arms with a sprocket-wheel provided with two pins on its face, and a lever operated by the pins on the sprocketwheel and connected with the registering device, snbstantially as shown and described.

2. In a weighing and registering apparatus, the combination of a cylinder having two compartments,trunnions attached to the same,pivoted arms support in g the eyli nder, and a weighing-beam connected to the pivoted arms with two sprocket-wheels connected with each other by a chain, an arm adj ustable on the shaft otthe smaller sprocket wheel, an arm pivoted 'to the main frame, and an arm fulcrumed on one of the trunnions of the cylinder and connected to the aforesaid arm by a link, substantially as shown and described.

3. In a weighing and registering apparatus, the cylinder F, having the trunnions E and'E, the pivoted arms D, the weighing-beam J, provided with the weight K, and connected with the arms D bya link, I,in combination with the cam S, having the two teeth S and S, the pivoted arm T, the slide V connected to the lever V, attached to a link, U, and the chute XV, having the central partitionflV, substantially as shown and described.

4. In a grain weighing and registering apparatus, the cylinder F, provided with the trunnions E and E, the arms D, and the weighingbeam J, provided with the weight K, and connected with the arms D by means of the link I, in combination with the sprocket-wheel M, the sprocket-wheel N, connected by a chain, M, with the sprocket-wheel M, the shaft N, the arm N ,thc pivoted arm O,and the arm P, fulcrumed on the trunnion E, and connected to the pivoted arm 0 by alink, 0 substantially as shown and described. 4

5. In a grain weighing and registering apparatus, the cylinder F, having the trunnions E and E, the arms D, the weighing-beam J, pro vided with the weight K, and connected with the arms D by a link, I, and a stop, L, in combination with the sprocket-wheel M, the pins Q'and- Q, and the lever R, operating the registering apparatus R, substantially as shown and described.

6. In a grain weighing and registering apparatus, the cylinder F, provided with the trunnions E and E, the sprocket-wheel M, the chain M, the sprocket-wheel N, mounted 011 the shaft N, and the arm N adjustable by a set-screw on the shaft N, in combination with the arm P, the link 0 and the pivoted arm 0, substantially as shown and described.

7. In a grain weighing and registering apparatus, the cylinder F, provided with the trunnions E and E,and the cam S',having the teeth- S and S", in combination with the lever T, the link U the lever V, the slide V connected with the lever V by the links V, and the chute \V, provided with the central partition, W, having the sharp inner edge, \V, substantially as shown and described.
